Given numbers are 426, 309, 37, 391

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(426, 309) = 43878

GCD(426, 309) = ( 426 x 309 ) / 43878

= 426 / 309

= 426

Step2:

LCM(3, 37) = 111

GCD(3, 37) = ( 3 x 37 ) / 111

= 3 / 37

= 3

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 426, 309, 37, 391 is 1
